The 30 mA sensitivity covers personnel protection against line-to-ground faults on AC circuits, while the C curve handles moderate inrush from motorized or fluorescent loads without nuisance tripping. Solid or stranded conductors from 0.75 to 35 mm² are accepted under the screw terminals; tighten to 2.5–3 N·m. Mechanical endurance is 10 000 switching cycles typical. Surge current withstand is 1 kA (8/20 μs waveform). Overvoltage category III, energy limiting class 3. Halogen-free and silicon-free construction. Touch protection is built in.","metaTitle":"Siemens 5SU1353-1WM25 SENTRON RCBO, 25A C-curve 30mA AC type","metaDescription":"Siemens 5SU1353-1WM25 SENTRON RCBO, 25A rated, C tripping characteristic, 30mA AC residual current, 4.5kA (EN 60898) / 15kA (IEC 60947-2), 1P+N, 2 MW, current lifecycle stage, avai","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Residual Current Breakers (RCCB/RCBO)"],"specifications":{"Solid":"0.75 ... 35 mm²","Maximum":"10.2 W","Stranded":"0.75 ... 35 mm²","Halogen-Free":"Yes","Silicon-Free":"Yes","During Storage":"-40 ... +75 °C","Number of poles":"2","Type of voltage":"AC","lifecycle_stage":"current","Mounting position":"any","Installation depth":"70 mm","Product brand name":"SENTRON","Ambient temperature":"-25 ... +55 °C","Product designation":"RCBO","Protection class IP":"IP20, if the distribution board is installed, with connected conductors","Overvoltage category":"III","Design of the product":"Instantaneous","Energy limiting class":"3","Number of width units":"2","Type of fault current":"AC","Number of poles / Note":"1P+N","acc. to DIN EN 61346-2":"F","acc. to DIN EN 81346-2":"F","circuit-breaker / Design":"5SU1","Current / at AC / rated value":"25 A","Tripping characteristic class":"C","acc. to EN 60898 / rated value":"4.5 kA","For Testing Equipment / Minimum":"195 V","Position / of power supply cord":"Either top or bottom","Number of poles / with protection":"1","acc. to IEC 60947-2 / rated value":"15 kA","Product feature / Touch protection":"Yes","Supply voltage frequency / rated value":"50 Hz","Tripping residual current / rated value":"30 mA","Influence of the surrounding temperature":"Max. 95% humidity","Surge current resistance / at (8/20) μs":"1 kA","Tightening torque / with screw-type terminals":"2.5 ... 3 N·m","Product function / neutral conductor switching":"Yes","Mechanical service life (switching cycles) / typical":"10 000"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=532139&mlfb=5SU1353-1WM25","alternativesUrl":"https://aoctrl.com/api/mcp/products/5SU1353-1WM25/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source to 5SU1353-1WM25?","answer":"Within the SENTRON family, the 5SL6563-7BB is the closest functional peer — same 25 A C-curve, 30 mA AC type, 1P+N configuration.
